Pancreas after islet (PAI) transplantation is a treatment option for patients seeking insulin independence through a whole-organ transplant after a failed cellular transplant. This report from the International Pancreas Transplant Registry (IPTR) and the United Network for Organ Sharing (UNOS) studied PAI transplant outcomes over a 10-year time period. Forty recipients of a failed alloislet transplant subsequently underwent pancreas transplant alone (50%), pancreas after previous kidney transplant (22.5%), or simultaneous pancreas and kidney (SPK) transplant (27.5%). Graft and patient survival rates were not statistically significantly different compared with matched primary pancreas transplants. Regardless of the recipient category, overall 1- and 5-year PAI patient survival rates for all 40 cases were 97% and 83%, respectively; graft survival rates were 84% and 65%, respectively. A failed previous islet transplant had no negative impact on kidney graft survival in the SPK category: It was the same as for primary SPK transplants. According to this IPTR/UNOS analysis, a PAI transplant is a safe procedure with low recipient mortality, high graft-function rates in both the short and long term and excellent kidney graft outcomes. Patients with a failed islet transplant should know about this alternative in their quest for insulin independence through transplantation.
